Sub-clustering of neutrophils identified six distinct subpopulations, based on the most prominently expressed genes, including CAMP, CAMK1D, PI3, MMP9, ISG15, FOLR3 in T2DM and T2DKD patients (Figures 2A–C, Supplementary Table 3). The gene discussed is CAMK1D; the disease is type 2 diabetes mellitus.
